Energy: End of Unit Test

What form of energy comes from a battery operated device?

• Electrical

• Motion

• Thermal

• Chemical

Which statement is NOT true about a battery operated flashlight?

• The flashlight converts chemical energy into light energy

• The flashlight uses light energy to produce chemical energy

• The flashlight produces both light and thermal energy

• The flashlight produces light energy by converting chemical energy from the battery

If the flashlight stopped working, what would be the best explanation and solution to the problem?

• The flashlight ran out of light energy and needs to be rewired

• The flashlight must be connected to a solar panel so that it has light energy to function

• The flashlight needs thermal energy to work so the batteries need to be changed

• The flashlight ran out of the chemical energy it was converting from the batteries, so the batteries need to be changed
